PART 1048_CONTROL OF EMISSIONS FROM NEW, LARGE NONROAD SPARK-IGNITION
ENGINES--Table of Contents
Subpart C_Certifying Engine Families
Sec. 1048.205 What must I include in my application?
In your application, do all the following things unless we ask you
to send us less information:
(a) Describe the engine family's specifications and other basic
parameters of the engine's design. List the types of fuel you intend to
use to certify the engine family (for example, gasoline, liquefied
petroleum gas, methanol, or natural gas).
(b) Explain how the emission-control systems operate.
(1) Describe in detail all the system components for controlling
exhaust emissions, including auxiliary emission-control devices and all
fuel-system components you will install on any production or test
engine. Explain why any auxiliary emission-control devices are not
defeat devices (see Sec. 1048.115(g)). Do not include detailed
calibrations for components unless we ask for them.
(2) Describe the evaporative emission controls.
(c) Explain how the engine diagnostic system works, describing
especially the engine conditions (with the corresponding diagnostic
trouble codes) that cause the malfunction-indicator light to go on.
Propose what you consider to be extreme conditions under which the
diagnostic system should disregard trouble codes, as described in Sec.
1048.110.
(d) Describe the engines you selected for testing and the reasons
for selecting them.
(e) Describe any special or alternate test procedures you used (see
Sec. 1048.501).
(f) Describe how you operated the engine or vehicle prior to
testing, including the duty cycle and the number of engine operating
hours used to stabilize emission levels. Describe any scheduled
maintenance you did.
(g) List the specifications of the test fuel to show that it falls
within the required ranges we specify in 40 CFR part 1065, subpart C.
(h) Identify the engine family's useful life.
(i) Propose maintenance and use instructions for the ultimate buyer
of each new nonroad engine (see Sec. 1048.125).
(j) Propose emission-related installation instructions if you sell
engines for someone else to install in a piece of nonroad equipment (see
Sec. 1048.130).
(k) Identify each high-cost warranted part and show us how you
calculated its replacement cost, including the estimated retail cost of
the part, labor rates, and labor hours to diagnose and replace defective
parts.
(l) Propose an emission control information label.
(m) Present emission data to show that you meet emission standards.
(1) Present exhaust emission data for HC, NOX, and CO on
a test engine to show your engines meet the duty-cycle emission
standards we specify in Sec. 1048.101(a) and (b). Show these figures
before and after applying deterioration factors for each engine.
Starting in the 2007 model year, identify the duty-cycle emission
standards to which you are certifying engines in the engine family.
Include test data for each type of fuel from 40 CFR part 1065, subpart
C, on which you intend for engines in
[[Page 556]]
the engine family to operate (for example, gasoline, liquefied petroleum
gas, methanol, or natural gas). If we specify more than one grade of any
fuel type (for example, a summer grade and winter grade of gasoline),
you only need to submit test data for one grade, unless the regulations
of this part specify otherwise for your engine. Note that Sec. 1048.235
allows you to submit an application in certain cases without new
emission data.
(2) If your engine family includes a volatile liquid fuel (and you
do not use design-based certification under Sec. 1048.245) present
evaporative test data to show your vehicles meet the evaporative
emission standards we specify in subpart B of this part. Show these
figures before and after applying deterioration factors, where
applicable.
(n) Report all test results, including those from invalid tests or
from any nonstandard tests (such as measurements based on exhaust
concentrations in parts per million).
(o) Identify the engine family's deterioration factors and describe
how you developed them. Present any emission test data you used for
this.
(p) Describe all adjustable operating parameters (see Sec.
1048.115(e)), including the following:
(1) The nominal or recommended setting.
(2) The intended physically adjustable range, including production
tolerances if they affect the range.
(3) The limits or stops used to establish adjustable ranges.
(q) Describe everything we need to read and interpret all the
information broadcast by an engine's onboard computers and electronic
control modules and state that you will give us any hardware or tools we
would need to do this. You may reference any appropriate publicly
released standards that define conventions for these messages and
parameters. Format your information consistent with publicly released
standards.
(r) State whether your engine will operate in variable-speed
applications, constant-speed applications, or both. If your
certification covers only constant-speed or only variable-speed
applications, describe how you will prevent use of these engines in the
applications for which they are not certified.
(s) Starting in the 2007 model year, state that all the engines in
the engine family comply with the field-testing emission standards we
specify in Sec. 1048.101(c) for all normal operation and use (see Sec.
1048.515). Describe in detail any testing, engineering analysis, or
other information on which you base this statement.
(t) State that you operated your test engines according to the
specified procedures and test parameters using the fuels described in
the application to show you meet the requirements of this part.
(u) State unconditionally that all the engines in the engine family
comply with the requirements of this part, other referenced parts, and
the Clean Air Act.
(v) Include estimates of U.S.-directed production volumes.
(w) Show us how to modify your production engines to measure
emissions in the field (see Sec. 1048.115(d)).
(x) Add other information to help us evaluate your application if we
ask for it.
